After the latest upgrade to ATV 2nd Gen (Black) and iOS 9.0.2, the AirPlay is not working on various apps (YouTube, Browser, etc.) My iPad sees the AppleTV (icon looks like an Audio AirPlay, almost like an iPod icon) and I can select it, but the video doesn’t display. Strangely, the Audio goes through and presents itself as an “Internet Radio” as the AppleTV’s screen switches to Music mode with no title or album art, while the video is still playing on the iPad. But no video on AppleTV.
Also when I select the AppleTV, the “Mirroring” option is missing.
Both these options were available prior to the last update of ATV and/or iOS 9.0.2
** Update: Resetting AppleTV to its original factory setting (without ATV Flash), the problem went away. iPad sees the AppleTV, can AirPlay to it and Mirroring option is available and functioning.
